It is a very common surgery, which became a routine operation lately. It is normally carried out when either there is not enough bone in the upper jaw or when the sinuses are too close to the jaw to put dental implants.
Bio-oss, a bone substitute material which is of bovin origin is added between the jaw and the maxillary sinuses. In order to do this the sinus membrane is moved higher. The Dentist then injects the Bio-oss and waits for the osseointegration.
This procedure can be performed by your certified dentist in the office. It involves choosing the bone grafting material. It could be autograft, in that case the bone is taken from the patient who is having the procedure, usually from the jaw or the hip bone. We do not do hip bone surgeries in our dental clinic but we have connections with a hospital in Szeged where this kind of surgery is done. If this occurs patient has to come to Hungary a week in advance for further examinations.
Another option they can choose is allograft material, which is harvested bone from another human. In this case the harvested bone is disinfected carefully and processed to ensure no bacteria or disease are passed on to the person receiving the bone graft.
Another option is Xenograft which is taken from animals, usually cows.
The process begins with numbing the area with local anesthetic and an incision is made in the gum to expose the bone. The surgeon then attaches the bone grafting material to the exposed bone in the mouth. The graft aids the body in preserving existing bone and making new bone (osseointegration).
